Description
Technical field
The present invention relates to a kind of rose cutter, and in particular to one kind splicing mould milling rose cutter, specifically for processing
Splicing mould has the helical edges rose cutter with land chamfered edge that impact-resistant abrasion-proof is damaged.
Background technology
Rose cutter is that being assemblied on milling machine for the similar bulb of blade is used for the various curved surfaces of milling, the cutter of arc groove.
Rose cutter is also R knives.Rose cutter can normal operation in high temperature environments.Rose cutter can be used for all trades and professions.
What is used in the finishing for splicing mould to automobile panel at present is a kind of monoblock type rose cutter, this kind of cutter
During processing and splicing part, complicated in the Milling Process characteristic of splicing transition region, abrasion and the breakage that there is cutter are serious
Shortcoming, it is necessary to reface after monoblock type rose cutter is in cutting edge event of blade failure, or can not use；If in processing automobile
When covering splices mould, although timely can be carried out more to blade using after the abrasion of indexable milling cutter tool or breakage
Change, but ordinary blade sword line is straight line, cutting force is big in straight sword working angles, big so as to cause, crudy is poor, add for vibration
Work precision is low and cutter life is low, adds the use cost of cutter, reduces processing efficiency.
The content of the invention
The present invention provides a kind of splicing mould milling rose cutter, is cut with solving existing indexable milling cutter working angles
Cut power big, vibration is big, cause tool wear serious, the problem of crudy is poor.
The present invention adopts the technical scheme that to solve the above problems：
One kind splicing mould milling rose cutter, it includes knife bar and cutter hub, and cutter hub is connected with knife bar；Have on cutter hub
Helical cutting edge；The cutting edge is cutting edge one and cutting edge two respectively；
It is knife face one after rake face one, major first flank one and second that the both sides of cutting edge one, which have,；
It is knife face two after rake face two, major first flank two and second that the both sides of cutting edge two, which have,；
The upper surface of cutter hub is connected with main line curved surface one and counter drain groove curved surface two respectively, the rake face one with it is described
The transition portion of main line curved surface one is chip pocket one, and the counter drain groove curved surface two is connected with knife face two after described second；
The lower surface of cutter hub is connected with main line curved surface two and counter drain groove curved surface one respectively, the rake face two with it is described
The transition portion of main line curved surface two is chip pocket two, and the counter drain groove curved surface one is connected with knife face one after described second.
The beneficial effects of the invention are as follows：
Rose cutter cutting edge of the present invention uses helical edges, and cutter tooth is gradually switched in and out along cutting edge, vibrates small, raising
The stationarity and the machined surface quality of workpiece of working angles；It can meet and complex space curved surfaces are processed with axial feed
Requirement.
Cutting edge of the present invention is that the cutting edge inclination of each point on helical edges, cutting edge is different, due to the effect of cutting edge inclination, can make to cut
Bits are smoothly discharged along cutting edge direction outer direction, effectively can prevent chip from sticking on sword, it is to avoid blade is damaged.
The present invention is in mould finishing passes when can timely be changed after tool wear, originally using clip type blade
Invention can reach the Mass accuracy of monoblock type rose cutter processing mold, there is the convenient of clip type blade tool changing again.

Embodiment
Further illustrate the present invention below in conjunction with the accompanying drawings and by embodiment.
Illustrate referring to Fig. 1 to Figure 10, one kind splicing mould milling rose cutter, it includes knife bar D and cutter hub F, knife bar D
With cutter hub F with being connected；There is helical cutting edge on cutter hub F；
The cutting edge is cutting edge 1 and cutting edge 2 15 respectively；
It is knife face 1 after rake face 1, major first flank one 3 and second that the both sides of cutting edge 1, which have,；
It is knife face 2 12 after rake face 2 17, major first flank 2 13 and second that the both sides of cutting edge 2 15, which have,；
Cutter hub F upper surface 10 is connected with main line curved surface 1 and counter drain groove curved surface 2 11 respectively, the rake face 1
Transition portion with the main line curved surface 1 is knife face two after chip pocket 1, the counter drain groove curved surface 2 11 and described second
12 are connected；
Cutter hub F lower surface 20 is connected with main line curved surface 2 19 and counter drain groove curved surface 1 respectively, the rake face two
17 be knife after chip pocket 2 18, the counter drain groove curved surface 1 and described second with the transition portion of the main line curved surface 2 19
Face 1 is connected.
Cutting edge 1 and cutting edge 2 15 are helical edges, and the cutting edge that cutting edge 1 and cutting edge 2 15 are constituted is rendered as
Spiral shape, plane projection is in serpentine.
Illustrate referring to Fig. 3, the chip pocket 1 and the chip pocket 2 18 are helical chip groove.It is arranged such, holds bits
Groove plays a part of holding bits, chip removal and control chip-flowing.Helical chip groove can control chip-flowing, and guiding chip is stable
Curling.
Illustrate referring to Fig. 1 and Fig. 2, in order to improve shock resistance and the wear resistance of cutter.On cutter hub F also have land and
Chamfered edge；Land 1 is provided between cutting edge 1 and major first flank 1, chamfered edge is provided between cutting edge 1 and rake face 1
One 5；Land 2 14 is provided between cutting edge 2 15 and major first flank 2 13, is provided between cutting edge 2 15 and rake face 2 17
Chamfered edge 2 16.
Fig. 3 and Fig. 4 explanations are participated in, chamfered edge 1, chamfered edge 2 16, land 1 and land 2 14 are helical structure, fallen
The width of rib 1 from point of a knife to knife bar direction along spiral winding to gradually increasing, the width of land 1 is by point of a knife to knife bar direction
Along spiral winding to equal, the width of chamfered edge 2 16 from point of a knife to knife bar direction along spiral winding to gradually increasing, land 2 14
Width from point of a knife to knife bar direction along spiral winding to equal.Margin width is equal, both can guarantee that reaching cutting force successively decreases
Effect, can be uniformly distributed cutting force again, so as to improve crudy, and the gradual change of chamfered edge width is determined by cutter structure
, there is the mathematical derivation formula of complexity.
